Florida Keys Overseas Heritage Trail

Trail Map

Description Suggest an Edit

The 106.5-mile Florida Keys Overseas Heritage Trail (FKOHT) will stretch the length of the Florida Keys, from Key Largo to Key West, the southernmost point of the continental United States. The trail is also part of a larger effort called the East Coast Greenway, which will link multi-use trails from Florida all the way to Maine.

Currently, more than 75 miles of the FKOHT have been paved and completed. For the rest, users will have to share the road with vehicles. The trail runs parallel to US Highway 1. Use extreme caution as some areas have narrow shoulders, causing potentially dangerous traffic encounters. The trail is also quite exposed, so bring lots of sunscreen.

Tracing the course of Henry Flagler's old railroad line, FKOHT includes 23 of the rail bridges, the longest of which is 7 miles. Some of these have been converted back to their original configuration, but with added safety rails and an asphalt surface. To accommodate fishing, platforms have been added to some of the reconditioned spans, including the 2.2-mile Long Key Bridge and smaller spans at Channel 2, Toms Harbor, and Toms Harbor Cut. In addition, the trail links a number of superb natural areas and historic sites.

Some highlights include:

  • Lower Matacumbe Key to Channel 5 historic bridge, 5.5 miles (MM 72-MM 77.5)
  • Long Key Trail & Bridge, 2.2 miles (MM 65-MM 68.5)
  • Grassy Key Trail, 4 miles (MM 54.5-MM 58.5)
  • Toms Harbor/Toms Harbor Cut, 5 miles (MM 60.5-MM 61.5)
  • Saddlebunch Trail, 4 miles (MM 11-MM15)
  • Knight's Key Trailhead to Pigeon Key, 2 miles (MM45-MM 47)
  • Dagny Johnson Key Largo Hammock State Park
  • John Pennekamp Coral Reef State Park
  • Windley Key Fossil Reef Geological State Park
  • Indian Key Historic State Park
  • Lignumvitae Key Botanical State Park
  • San Pedro Underwater Archaeological Preserve
  • Curry Hammock State Park
  • Bahia Honda State Park
  • Fort Zachary Taylor Historic State Park
